I've seen some useful set builders and damage/shield calculators but I can't remember where so I'll look around and add them later. Feel free to add other useful links and I'll update this post with them

If you are looking for historical lore then Krosmoz.wikia.com a nice source that seems mostly in date, alternatively 1d4chan but be warned this was set up by 4chan (you'll need more than a pinch of salt)
